What Is a Casino?

A casino is an establishment for certain types of gambling. Many casinos are combined with hotels, resorts, restaurants, retail shops, and other tourist attractions. Some casinos are also known for hosting live entertainment, such as stand-up comedy, concerts, and sports events. The term casino may also refer to a specific game, such as blackjack or roulette, which is commonly found in casinos. The precise origin of gambling is unknown, but it can be traced back to ancient times. There are records of gambling in Babylon, Rome, Greece, and China. Modern casinos offer a wide variety of games, including poker, baccarat, roulette, blackjack, and craps. Many casinos are located in cities with large populations, but some are in smaller towns.

Security is a major concern of casino owners, given the large amounts of money handled within a casino. Consequently, many casinos have extensive measures to deter cheating and theft by both patrons and employees. The most basic measure is to have cameras monitoring the entire casino floor. Casinos also use other technology to monitor the games themselves: betting chips with built-in microcircuitry allow the casinos to track the amount of money placed at each table minute by minute; and roulette wheels are electronically monitored to discover any statistical deviation from expected results.

Some casinos have special rooms for high-stakes gamblers, who are generally allowed to place bets in the tens of thousands of dollars. These rooms are often located in buildings separate from the main casino and are staffed by people who are trained to recognize certain betting patterns. In addition, these gamblers are usually rewarded with comps such as free hotel rooms and meals.
